BUNG FOR BARRELS, 84c.

SPECIFICATION forming part of Letters Patent No. 248,347, dated October18, 1881.

Application filed March 28, 1881. (No model.)

To all whom it may concern:

Be it known that I, TITUS POWERS, of the city and county of New York,State of New York, have invented a new and useful Improve inentin BungsforBarrels, of which the following is a specification, reference beingbad to the accompanying drawings, forming part of the same, in whichFigure l is a plan or upper-face view of a bung containing my invention.Fig. 2 is a central longitudinal sectional view of the same. Fig. 3 is asimilar sectional .view of the casing of the same, with the central plugreversed. Fig. 4 is an external side view of said plug. Fig. 5 is a topview of the same. Fig. 6 is a face view of the lower end of said plug.Fig. 7 is a view of the screw-up valve; and Fig. 8 is a section of saidplug, cut on the line a 00, Fig. 4.

My invention relates to a hung provided with a vent that is controlledby a valve, which permits the admission of air into the cask to which itis applied and prevents its escape therefrom.

My bung consists of four principal parts-- viz., first, the case orbushing fitted to be secured tightly in the bung-hole of the cask;second, a main plug fitted into said case and forming an air-tight jointtherewith, and removable at pleasure; third, a vent-plug within the mainplug; fourth, valves connected with the vent-plugfor controlling thevent, the same being a screw-up valve at the lower end of said ventplug,the stem of which extends through the plug, and the upper end beingprovided with a screw-thread, and a broad-faced nut, which constitutes adisk-valve that controls the upper end of the vent-hole in the plug, andalso a flexible automatic valve in the said vent-plug intermediate withthe said screw-up valve and said disk-valve.

A is a case or bushing provided with a screwthread on its outer surface,and preferably made tapering, adapted to be screwed tightly into thebung-hole of a barrel or keg. At the upper end are two segments, a a, ofan in wardly-projecting annular flange. At the lower end of this casethere is an inwardly-projecting flange, b, that forms a seat for themain plug B, which is itself a shell or case provided with a perforateddiaphragm, c, and a shoulder, d,

that sets down upon the flange b, and, with suitable packing, 6, forms atight joint therewith when the plug is pressed forcibly upon it. At thethe upper end of said plug are laterally-1: rojecting lugsff withinclined upper surfaces, as seen in Fig. 4, adapted to pass down betweenthe segments a a when the plug is insertedjn bushing A, and to passunder the segments when the plug is turned, and thus lock the plugfirmly down on the packing e.

O is a screw-up valve, the stem at of which passes up through a centralopening in the di-v aphragm c, a screw-thread being cut on the upper endthat is provided with a nut, 9, that has a broad flange, b, which restson the diaphragm c and constitutes a disk-valve thereon. A smallaperture, t', is made through the said diaphragm, and the said flangehis provided with a corresponding aperture, 45, the two apertures, wherethey coincide, constituting a vent-opening through the'said plug, such"out being closed by turning the flange It so that the two apertures donot coincide. The lower end of the bushing A constitutes the seat of thevalve 0, an air-tight joint being formed between them by suitablepacking,j. The motion of the flange h is limited by a stop-pin in, fixedin the interior of the bushing A, near its upper end, and 'a projectingsegment, I, on the perimeter of flange h. These parts are so made andproportioned that when the nut g is turned so thatoneend ofsaid segmentlstrikes against the pin k the said nut is screwed down, thereby drawingup valve 0 and closing the joint atj, and at the same time closing theaperture t', and when turned so that the opposite end of said segmentstrikes against said stop-pin the vent i is opened and the nut g is.runback on the stem on, so thatthe valve 0 drops down, thus openingthejoint atj.

The screw-up valve 0 and its stem at are prevented from turning in themain plug B,

with the nut g, by means of the notches s in the central opening, 75, inthe main plug B, as seen in Fig. 5, and radial projections s on the baseof the stem m, as seen in Figs. 6 and 7,

that fit into said notches.

n is a flexible valve, preferably a disk of rubber having a centralopening, permitting it to be put onto the stem of valve 0 and be held inan annular groove, 0, Fig. 7. An annular projection,s, ontheunder sideof the diaphragm 0, forms a seat for this flexible valve, so thatpressure on the upper side will throw it down onto the upper face ofvalve 0, and thus permit air to pass down through the jointj, when thatjoint is open.

Fig. 8 shows several recesses, 12, made in the inner face of the plug13, to receive a suitablyformed winch to be used in turning'said plug inthe bushing A.

The application and operation of this bun g are as follows: A bung-holeof suitable size being made in the barrel or keg, the bushing A isscrewed into it, so as to form an air-tight joint. The plug B not beingyet inserted the barrel may be filled through the bushing. Then the plugis inserted and secured, and the nutg, with the disk h, is turned so asto draw up the valve 0 and close the joint j, and also close the vent1'. Then, when the contents of the barrel are being drawn off and a ventis required, the nut g is turned back, so as to allow the valve G tofall away from its seat and at the same time open the vent-hole i, thuspermitting air to pass through the said vent-hole and joint Then, if thepressure ofair or gas in the barrel overbalances the pressure of theexternal atmosphere, the flexible valve or will be closed by suchinterior pressure and the cs 0 cape of gas prevented.

The bung which Ihave described is an improvement on that for whichUnited States Letters Patent No. 232,903 were granted to me October 5,1880.

What I claim as new, and desire to secure by Letters Patent, is-

1. A hung in which are the bushing A, the plugB,provided withthediaphragmc,provided with a vent-hole, i, the valve (J, the stem m ofwhich is provided with a screw-thread, the nut 9, having flange h,provided with a vent-hole, i, and the flexible valve n, all constructedand combined to operate as and for the purpose described.

2. The combination, in a hung, of the plug B, having the venteddiaphragm a, valve G, nut 9. having the vented flange h, provided withthe segmental projection l, and the stoppin it, all constructed andarranged to operate as and for the purpose described.

In witness whereof I have hereunto set my hand, March 7,1881.
